OK so i have a 2003 dodge ram 1500 5.7 hemi rwd with a 3 inch suspension lift kit i want to go bigger with tires and i wanted to get some input. i right now have stock rims with 246/70/r17 i am looking at new Black Rock Type 8 17x9 -12 offset rims and Cooper Discoverer S/T MAXX Radial Tire - 295/70R17 121Q tires. they would make it out to be 33'' tires. here is a link so you can see the info of both tire and rim.
so im trying to find out if they will fit my truck and look good!!! with no rubbing or any problems i don't really off-road but i do haul trailers and stuff "i do have airbags" . and will i have to get the truck re-geared.
I like the look of the rim, the offset will certainly move the tire outward. Tire looks good. Factory 20" tires if I remember correctly are 33" tall and the rim has a 6" bs. This i would think will move the edge of the tire to just outside the fender edge. IMO, most definitely needs 4:56 gear to maintain performance and save the transmission.
those are nice. so i looked into getting regeared its gonna cost me 1200 and i only need rear. the tires i want were 295/70r17 you guys think id need to regear if i did 285/70r17
The 295 should fit fine, -12 isn't that much offset, roughly 1/2" and the stock rims are 17x9 too so no drastic changes there.
What gear ratio do you have right now? I had an '06 2500 that I put 285x70r17 on that had 4.10 gears. Definitely noticed a little difference going from a 265 but nothing drastic.
Something that you'll have to keep in mind is that you may want to get a tuner capable of calibrating the speedometer or a speedometer calibrator for the tire size change. You don't need to worry about the re-gear messing it up because the reluctor is on the ring gear :thumb:
I checked my sticker mine 3.55 its my work truck im a contractor so i haul stuff i dont race or offroad inless in the mountains so a -12 is only 1/2 inch crap... i need at least 1.5 inches want the tires to stick out i have fender flares wanted to fill the void.... finding a good rim and tire is a pain in the ***
-12 is considerably farther out than stock, which is something like +25. That will make your change -37mm +/-. Further out than that and hauling "stuff" will wreak havoc with your wheel bearings, an' they ain't cheap to change.
be careful with too much offset, especially in the front. For every mm you move the tire out with offset, you also move it forward in the front wheel well.....when the wheel is turned. This would mean that the tires will clear when straight, but hit the front bumper when turned. It's a delicate balance.
i ran 17x9 with 315 wides on a 2mm offset, had decent stickout, clearance will be no issue.
